Just wondering what the largest size motor we can drop in our thirdgens is?? Just lookin at the newest Chevy Rumble mag and am lovin the 454 thats runnin 532HP/525Ft #'s on 92 octane

 

Any size you can afford.

 

The biggest shortdeck BBC is 540 cid.

 

Correction. I just found a bigger engine. Keeping with the short 9.8" deck height and using a 4.5" bore the Merlin block can go out to 540 CID.

Keith Black makes a 9.8" deck height, 4.5" bore aluminum block that can take a 5" stroke crank. That would make the biggest short deck height block a 636 CID engine.

If you found some way to make a tall deck 10.2" block fit easily, 700+ cubic inches is easy to obtain.

With a "mild" camshaft that would easily make over 500 hp on pump gas.

 

Kind of an open ended question but what I think you're looking to hear is - big block Chevy.

 

Damn dude, a blown Big Block, that's awesome. Please tell me that's an aftermarket 5 speed you have and not the original T-5, otherwise you may have become my new hero (if the T-5 is still alive that is).

 

Tremec TKO 5-speed. Actually, the Tremec has been put aside for a TH400. Some things are just better done with an auto.

I am building a 638 powered T/A that should be running late February.
